DEVICE FOR TRANSMITTING POWER..

SPECIFICATION forming part of Letters Patent No. 354,692, dated December21, 1886.

Application filed July 29, 1886. Serial No. 209,418. (No model.)

To all whom it may concern:

Be it known that I, THOMAS H. CONNELLY, a citizen of the United States,residing at Phoenix Park, in the county of Schuylkill and State ofPennsylvania, have invented certain new and useful Improvements inDevices for Transmitting Power; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to devices for communicating motion from one pointto another at a distance therefrom, and while applicable to manysituations is particularly useful in transmitting power from an outsidesourceto pumping or other machinery located within mines or like placeswhere economy of space is desired, or where it would be impossible orinconvenient to have the engine proper or other motive power.

My object is to provide a simple and economical mechanism fortransmitting the power from an engine or other source located outside ofthe mine to a machine'or machinery within the same through anintermediate cable and frame, which may be of any extent to correspondto the depth of the mine.

The invention consists, primarily, of an oscillating frame composed oftwo end pieces centrally mounted, one at the surface and one in themine, their ends being connected by cables with a suitable connection atone or both ends of each of the oscillating end pieces,

whereby at the upper part motion is communicated to the frame, and atthe lower end transmitted to the machinery within the mine or otherplace.

In the drawings, Figure 1 represents the driving machinery locatedoutside of the'mine, with the frame for transmitting the power to theinterior of the mine. Fig. 2 represents a side elevation of the frame,showing the supporting-timbers in section.

It will be understood that while I have shown the mechanism as arrangedvertically, it may be located horizontally or at an angle, though thelatter situation would probably prove rare.

In the figures, A represents the driving-shaft of the engine or othermotive power located outside of the mine or similar place where mynection.

invention would be used; and B represents the beveled gear mounted onsaid shaft meshing with a crown-wheel, 0, having a wrist-pin set in itsface, to which is secured a pitman, D. Instead of the connectionsdescribed,it will be obvious that other and equally well-knownattachments may be used for the purpose.

The pitman D is connected at its lower end to one corner of the frame E,and gives a vibratory movement to the frame proper, but a verticalreciprocating movement to the longitudinal sides thereof. This frame iscomposed of the end pieces, a a, one being located at the entrance tothe mine or in proximity thereto, while the other is arranged within themine or other place in convenient position to operate the machinerythrough suitable connections, similar to those above described, it beingunderstood that these end pieces must be in such relative positions asto be in direct line with each other. They are pivoted centrally ontrunnions d, as shown in Fig. 2, or in any other suitable manner. Theends of the pieces a a are connected by parallel cables 12 b,which arepivotally secured thereto, so that though the pieces a a move in the arcof a circle the parallel cables will be reciprocated vertically.

The cables are of the same length,and are provided with tighteningdevices, either such as those shown at c in Fig.2 or of any othersuitable for the purpose. The cables upon each side being drawn taut,itwill be seen that the power applied through the pitman D will betransmitted through the cables to the opposite end 'of the frame, andfrom thence; to the machinery to be driven,either by means of a pitman,K, as shown in Fig.1,or by other suitable con- The downward movement ofthe pitman, when connected to the left-hand end of the frame,will havethe effect of a push upon the cable of this side and a pull on that ofthe opposite side, and as both are taut there can be no slack, whateverhe the length of the ca bles.

In case the mechanism should be used at an angle or horizontally, itwould be desirable to use supporting and guiding pulleys for the cablesto take off any strain upon them.

Instead of having a pitman-connection at one corner of the frame,asecond pitman may beconnected with the opposite corner to give increasedpower, and the same arrangement may be provided below, so as to transmitthe power to two different machines or machinery without in any degreeimpairing the efficiency of the apparatus or lessening its power.

Having thus described my invention, what I claim,and desire to secure byLetters Patent of the United States, is-

A device for communicating motion,consisting of two straight rockingbeams, one arranged to receive motion from any source of power and theother to transmit the same, and intermediate cables arranged parallel toeach other throughout their whole extent between the rocking beams, andfixed directly to the inner opposite ends of said beams upon each sideof the pivotal point thereof, whereby a practically rigid frame isprovided, combined with suitable connections for receiving andtransmitting power, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
